I am moving a website from one hosting provider to another, and this of course means that I need to migrate all the mailboxes as well.
Do I have to manually move all the old emails from one server to another, or will all the email clients “save” a copy of the old emails on each computer?
Pardon, the naivety – I hope this additional info helps:
I’m doing this remotely, so I am not sure which email client(s) people will be using at the office, but I will need to be prepared for both POP and IMAP setups.
Also, the server they currently have is on VPS.net (cPanel), and we are migrating to a MediaTemple Dedicated Virtual (Plesk). Both Linux.
Your question depends on the configuration of each of your employees email clients. Hopefully the are set in a standard fashion and not all different. If they are configured to download and store emails locally, then your users already use the local copy. The emails most likely still exist on the server (unless your email client removes them which is common with POP3). If the users use a webmail interface to check email then there is no local copy and you will most certainly need to export. If you can give us a better example of how your employees check their email (web browser or name of the email client used) we can probably help further.
Edit: Also if you are currently using cPanel and want to be prepared for however clients have their email client setup, then just do the export. A quick google for “export email from cpanel” will show you the way.
